hello i set up a domain (domain.com) with virtualmin, but i cannot send email with mail() (not using any smtp), and i cannot receive email sent to for example firstname.lastname@example.org.
my domain is registered at another host company OVH, so the primary and secondary DNS server are at htis webhosting company 's. The dedicated server is at Onlline.
What should i do to make it work? the website is working because in the zone configuration the A record point to the ip of my dedicated server at Online.
What are the tweaking at OVH and Online to make mail() and the reception of email working?
thank you for your help !
